TIRE-RETAINING MECHANISM.

application filed November 17, 1913.

lie it known that we, MEYER Rosnnnnnrnn and. MEYER Huoo Rosmvnnrmnn, citizens of the United States, residing at Milwaukee, county oi. Milwaukee, and State of Wisconsin have invented new and useful Improve in 'lire-ltctaining h'lechanism, of he following is a specification.

Uni .avention relates to improvements in device. tor detachably holding tires in place on automobile wheels. r

The object of our invention is to provide a more simple and ellicient device, than has hcretotore been made, for fastening tires upon and detaching thorn from automobile wheels, whereby the labor of removing and ri-iplacing tires is greatly reduced.

()ur invention is further explained by reference to the accompanying drawings in which-- I Figure 1 represents a side view of an ordini. auton'iobile wheel provided with our tire rrl'aininp, device. Fig. it is a longitudinal section through a portion of the wheel folly and tire showing one of the tire rel ig. l is a transverse section drawn on line ;r---."r; of Fig. 1, and Fig. 4 is a tra'iaiverso section drawn on line 2 y of Fig. 1.

Like parts are identified by the same ref erence numerals throughout the several views.

The, wheel 1 and tire 2 are substantially of 1:5! EU/1.07131 it may concern which ordinary constru'ction; The invention here in is predicated more especially, as suggesteril, upon the mechanism ior detachably securing the tire in place upon the wheel.

'l'he tire 2 is provided upon the respective sides of its base with annular heads 3, 3 for the reception of the retaii'iing flanges 4, 4. The flanges l are each connected or formed integrally with the annular rim The flanges 4 and rim 5, when in place upon the tire, serve to retain the overlapping edges (5 and 7 of such tire together, as shown in Figs. and t. 'lhellanges -'l and rim 5 are adapted to be removed from and replaced upon the wheel together with the tire.

and is supported from the hub 9 by a plurality of spokes 10 in the ordinary manner. Surrounding the periphery of the folly 8 is an annular metallic rim. 11. The rim 11 is held firmly againstthe periphery 8 by a plurality olthimbles 12. The thirnhlcs 12 are each provided at their outer diverging ends with an annular flange 13 which flange bears against the periphery of the annular ril'n 11. Each of the threaded thimbles 12 are provided with a screw H. which has threaded hearings in said. thiinbles. The outer ends of the screws M are adapted to bear against the inner surface oi the angular projections or shoulders 30. Thus it is obvious that as the screw 1i is turned forward .in the threaded bearings of the thi'inble 12 against the shoulders 30, said thiuible 12, together with the flanges 13, will be drawn inwardly by said screw, whereby the annular flanges 13 are caused to bear against the opposing surface of the rim 11.. p

is an annular bracket which is adapted to bear against the inner surface of the telly S and against the respective. sides of said telly, T1111 '11 and shoulders 30. A spiral spring 18 is intcr 'iosed between the inner surface of the telly 8 and the inclosing brackets 15.

19 19 15) are nuts which have threaded hearings on the screws 14- and said nuts are adapted as they are turned down on said screws 14 against the brackets 15 to force said brackets 15 past the opposite sides of the shoulders 30, whereby said amiularriin and the'tire connected therewith are sccurely retained in place upon the wheel. lVhen it is desirous to remove the tire from the wheel the operator has simply to turn back the several nuts 1!) on said screws 1.4 when the brackets 17) will be forced in.- wardly by the recoil of said spiral spring 18 until. the outer edges 20, 20 of said brackets, are moved past the opposing side of the shoulders 30, whereby the tire and annular rim connected therewith can be readily removed from thewheel, while the bracket 15', together with the rim 11, is re tained in place upon the folly.

When a tire has been placed upon a wheel in the position first turned down in the thimbles 12 until the inner ends of said screws are brought within the V shaped groove 21. When this is done thenuts 19 are turned down on said screws 1 1 until the bracket 15 is forced outwardly past the respective sides of the shoulder 30, as shown in Figs. 3 and 4%, whereby the tire and its retaining rim are securely retained upon the felly and cannot be disengaged therefrom until said nuts 19 have been again turned back uPQI said screw 14. i

By the device shown in Fig. i a tubular member 23 is substituted for the screw 14 and an aperture is provided for said tubular member through the felly 8, rims 5 and 11 and shoulder 80, as shown in said figure. The exterior surface of said tubular member 23 is also provided with a nut 19 which has threaded bearings 011 the periphery of said tubular member and said nut is adapted to be turned down on saidtubular member against the opposing surface 'of the in connection with the tubular member 23, is preferably provided with a plurality of slots 24, 2d for the reception of the bolts 17, whereby it is obvious that when the nuts 26 have been turned back on said bolts 17 and said nut 19 has been turned back on said tubularmember 28, the bracket 15" and plate 16 may be readily moved out of contact with the shoulder 30 preparatory to removing the tire from the wheel. Said bracket 15, plate 16 and clamping bolts 17 are adapted v to be used with the tubular member 23 only.

The plate 16 is adapted to bear against the opposite sides of said felly and rims from the bracket 15 and said plate *16 and bracket 15 are retained in place upon the respective sides of said felly and rims by the clamping bolts 17. I

:27 is a thimble of ordinary construction which is adapted to be turned down over the inner end of the tubular member 23,

-Whereby the aperture 28 in said tubularmember is closed.

A groove or channel 29 is cut tubular member :23 corresponding in width with the diameterof such tubular member, reference being had to Fig. 4:. lVhen desirous to remove the tire the thimble 27 and nut 19 are first removed from the tubular member when the nuts 26,21 re turned back shown the screws 14 are lhe bracket 15, which is used v in the felly 8 and rim 11 upon the right hand side of the ing in a circular direction upon the support ing felly, we have provided the tire in closing rim 5 with a plurality of angular projections 80 and we have provided the felly inclosing rim 11 with a plurality of recesses 31 for the reception of said angular projections, as shown in Fig. 1, itbeing 1111- I 1.
